[Femoral head osteotomy for complex deformity after Legg-Calvé-Perthes disease].
Review in Orthopadie (Heidelberg, Germany), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Complex hip deformities after Legg-Calvé-Perthes disease are characterized by an enlarged, asymmetrically deformed femoral head, a short femoral neck, a high-riding greater trochanter, and secondary acetabular dysplasia. These features lead to intra- and extra-articular impingement, instability, abductor weakness, and early osteoarthritis. Conventional osteotomies or isolated acetabular reorientations do not directly address the femoral head deformity and, therefore, show limited results. Detailed analysis of the vascular anatomy enabled the development of intracapital osteotomy with central segment resection, without significantly compromising femoral head perfusion. Since 2001, this procedure, often combined with periacetabular osteotomy (PAO), has been used to restore sphericity and joint stability. Early data demonstrate significant radiological and functional improvements. Despite its technical complexity, the procedure is considered a promising option; long-term and multicenter studies are warranted.
